Abstract
Feedstock price and availability remain a barrier to adoption of cellulosic biofuels. Eucalyptus spp., can produce an energy-dense terpene suitable for high-density synthetic hydrocarbon-type fuel (grade JP-10) production in addition to cellulosic-based feedstock for traditional jet fuels (e.g., grade Jet A) and gasoline. This study modeled economic potential for Eucalyptus to fulfill US fuel markets. Cold-tolerant Eucalyptus was simulated in an annual coppice system for maximized leaf production. Results of the lowest simulated price ($110 t−1) show that within 10 years, there is potential to produce 204 million L yr−1 of fuel, including 51 million L yr−1 of JP-10-type fuel, 75 million L yr−1 of Jet A type fuel, and 77 million L yr−1 of gasoline. These quantities of fuel could be valued at approximately $500 million (USD), with feedstock costs totaling approximately $100 million (USD). Longer-term markets (to 20 years) or higher priced (to $220 t−1) scenarios show potential for more production. Research to determine potential for genetic improvement, delivered fuel costs, and biorefinery siting near existing infrastructure is recommended.

County-level per-hectare annual yields of energy crops are a key input variable to POLYSYS. Because Eucalyptus is not widely cultivated in the US, geographically explicit yields for Eucalyptus in the US is not well known. Yields of other energy crops have been empirically modeled based on results of the Sun Grant Regional Feedstock Partnership in collaboration with the Oregon State University PRISM modeling group [52]. Using yield data collected from more than one hundred field trials of energy crops collected from 2008 to 2014, county-specific per-hectare yields based on 30-year historic weather data were modeled in PRISM [53]. The Regional Feedstock Partnership modeled yields for energy crops including energy cane, switchgrass (upland and lowland), Miscanthus, poplar, biomass sorghum, and other energy crops. However, Eucalpytus field trial data from the Regional Feedstock Partnership lacked adequate geographic breadth to quantify statistically valid relationships in PRISM. Further, data on annually coppiced Eucalpytus field trials in the U.S, were unavailable and so.This research was funded by the US Department of Energy (DOE) under Award Number DE-15593.
